Growing defect free silicon crystals is one of the worlds top secrets. Our simulator can help you build your own secret to grow defect free crystals

Semiconductor crystal defects define the price of the crystal ingots in the market. Using the Defects engineering module of FEMAGSoft, crystal growers can predict the quality of the crystals grown in their furnace.

The defects engineering module provide crystal growers with an insight on the evolution of interstitial, vacancies and microvoids during the growth of Silicon or Germanium.

FEMAG-FZ can be your test playground to see the dependency and evolution of crystal quality based on the following operating conditions.

• Hot zone environment configuration
• Crystal and feed rod rotation rates
• Crystal pull speed, feed rod push speed

As one knows these dependency, one masters his process behavior and can find out the optimal setup saving time.
